good first issue

描述

Currently the unit tests are run against the transpiled code in the lib folder. This has a few issues:

  1. it increases the build / test time
  2. the test code can only use language features currently supported node
  3. the import statements in test code reference the transpiled output, which makes it hard to navigate failure stack traces.
  4. We don't have any flow-typing for the unit test code

Ideally mocha would be run through babel - with source maps.

研究方向
Examine the current test setup in package.json and any mocha configuration files. Modify the test script to run mocha with ` require @babel/register` and enable source maps. Ensure that babel is configured to transpile ES modules for Node. Test the changes by running the unit tests and verifying stack traces point to original source files.
